Error Integrating EWS 2.2 with Windows Phone 8.1 App

Question

Hi,
I am new to Windows Phone development. I have a basic need to access the Exchange Calendar.
I am using Windows Phone 8.1 SDK and Exchange Web Service 2.2 SDK.
As a first step I tried to use the
Microsoft.Exchange.WebServices.Autodiscover
dll to find the end points of the Exchange Server.
However on the first code statement
Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService
service = new
AutodiscoverService();
It throws an exception –
An exception of type 'System.IO.FileNotFoundException' occurred in Microsoft.Exchange.WebServices.DLL but was not handled in user code
'System.IO.FileNotFoundException' occurred in mscorlib.ni.dll
I further tried some debugging and using Code Analyser I get following warnings –
Microsoft.Exchange.WebServices.dll: warning CS1684: Reference to type 'System.Net.IPAddress' claims it is defined in 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\WindowsPhoneApp\v8.1\System.dll',
but it could not be found.
And
C:\Program Files\Microsoft\Exchange\Web Services\2.2\Microsoft.Exchange.WebServices.Auth.dll: warning MSB3817: The assembly "C:\Program Files\Microsoft\Exchange\Web Services\2.2\Microsoft.Exchange.WebServices.Auth.dll"
does not have a NeutralResourcesLanguageAttribute on it. To be used in an app package, portable libraries must define a NeutralResourcesLanguageAttribute on their main assembly (ie, the one containing code, not a satellite assembly).
I am not sure what the issue is, but when I try the same code it works in a Command Application. There are other errors but not the above ones. It at least executes few statements.
Can someone please help resolve this error and point me to links where I can find sample code with Windows Phone 8.1 implementation?
Thanks in Advance
Nasir

Answer 1

The EWS SDK 2.2 is a regular Desktop .Net DLL and therefore won't work in a WinRT App (CoreCLR). You should however be able to call the WebService directly.
